Data corruption is the damage of data because of various software or hardware fails. When a file is damaged, it will no longer function accurately, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, which makes it a significant problem for website hosting servers as fails are more likely to occur on bigger hard drives where vast volumes of information are placed. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and it'll be copied on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot identify corrupted files immediately or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
In case you host your sites in a shared web hosting
account from our firm, you don't need to worry about any of your data ever getting corrupted. We can ensure that since our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any information that you upload will be stored in a RAID i.e. simultaneously on numerous SSD drives. All file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file won't get corrupted. This can happen throughout the writing process on each drive and after that a bad copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives in real time and if a corrupted file is located, it's swapped with a good copy with the correct checksum from some other drive. In this way, your info will remain undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption because all our storage servers make use of the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives in a RAID i.e. the files shall be the same on all disk drives. All of the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it registers a mismatch, which will indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, extending the time needed for the server to go back online. ZFS is the file system that can really protect your content from silent data corruption.
